As part of the BATSS project mission to redefine safety and performance standards in next-generation battery systems, partners have achieved a key milestone: the completion of its of its Master Battery Management System (BMS) and Module Management System (MMS). These developments mark a tangible step forward in the project’s effort to create a highly efficient, modular, and intelligent control architecture for advanced battery applications.
The challenge: precision, reliability, and integration
Battery management lies at the heart of every energy storage system. The BMS must continuously monitor, protect, and balance the battery’s operation, from individual cells to the entire system.
Traditional systems, however, face limitations in scalability, communication speed, and fault tolerance, challenges that become even more complex when integrating new materials and architectures.
The innovation: a multi-layered, intelligent control system
The BATSS BMS introduces a two-tier wireless architecture:
- A Master BMS that supervises system-wide parameters, ensuring consistent operation and communication with external systems like converters.
- The MMS, a low power module controller that supports balancing currents up to 400mA.
The architecture enables a flexible and autonomous design with internal wireless RF communication based on the 2.4 GHz band, providing a secure and reliable communication channel. The BMS supports a variety of communication interfaces, such as CAN and Modbus RTU. Together, they form a robust and scalable control framework capable of managing advanced battery architectures while supporting improved energy efficiency and enhanced diagnostic capabilities.
The impact: reliability, safety, and scalability
By integrating advanced data processing and monitoring, the BATSS BMS improves system safety, thermal balance, and fault detection, ultimately extending the battery system’s lifetime.
The modular design also enables flexible adaptation to multiple applications, from electric vehicles to stationary energy systems, aligning with Europe’s goal of developing safer, more sustainable energy storage technologies.
Next steps
With the BMS prototypes completed and validated, partners are now refining integration and performance testing within downscaled and full-scale modules. These steps will lay the foundation for system-level validation and optimisation during the next project stages.
Stay tuned! BATSS results have just arrived; more to be reported soon!
